How to maintain the initial screen for creating a multiple BOM:
You see the Create material BOM initial screen.
You can only add an alternative to a simple material BOM (technical type = " ") or a multiple BOM (technical type = M).
Please note that the BOM for which you want to create an alternative must exist in the plant you enter here.
If a parameter for the Usage field is defined as a default value in your user master record, you see this value. Otherwise you see the last usage entered in this field.
When you select the Usage, please note that the usage defines which item statuses you can set. This means that you can only maintain specific indicators (for example, relevant to production, relevant to costing) at item level.
The material for which you want to create an alternative must already have a BOM in the selected plant with the Usage you enter here.
– If you want to assign a name to the alternative, enter an alphanumeric character string in the Alternative field.
– If you want the system to automatically assign a name to the alternative, do not make an entry in this field. The system automatically determines the next available alternative (numeric sequence).
If you create the alternative with reference to a change number, the BOM group (all alternatives of a multiple BOM) has a history requirement for all further changes.
This means that you can only change or extend the BOM if you enter a valid change number.
– If you enter a change number, the system determines the valid-from date of the BOM from the Valid from field in the change master record.
– If you want to change the BOM without reference to a change number , do not make an entry in the Change number field.
If your data is correct, you can copy data from an existing BOM.
